Users Manual

The Utility Wireless Meter will never be sold to the General public. The device will only be sold to and used by Commercial Utility companies. Installation is made directly by Schlumberger. For this reason a user manual will never be made available. .

RE: Schlumberger Resource Management FCC ID: F9CCMM1303 F9C25-1962 I really want to move on these Applications and am not willing to make you or your client wait any additional time for a response. I have thought long and on your proposed Grant notes and I am convinced that this is not the appropriate way to go. The TCB process was set up to handle “routine” equipment authorizations only. In the case of RF exposure we are given a set of “canned” statements, which are deemed appropriate for most equipment. And the Commission has made it very clear they do not want deviations by the TCBs from that text The definitions of Fixed, Mobile and Portable are very arbitrary. Fixed devices are placed on outdoor permanent structures at least two (and sometimes 10) meters away from all persons. Portable devices concern themselves with the near-field phenomenon associated with the maximum power density of jumbled E and H fields as they leave a radiating structure. At in-between distances you have the “Mobile” designation – or devices that operate with safe distances from 20 cm (~7 inches) to 2 meters (~6.5 feet). I propose we use the original Grant notes without changes. Response: Schlumberger will accept the mobile grant condition for these devices. I have also included an RF Hazard statement for this application just in case and a user manual statement.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 20, 2001 RE: Schlumberger Resource Management FCC ID: F9CCMM1303 I have a few comments on this Application. 1.) The Application lists only 917 MHz as the emission frequency. The Operational Description indicates it is useable over 902 to 928 MHz. If this is so, then three frequencies should have been tested according to 15.31(m). Please address. 2.) No manual – either installation or owners – was received. For a product which requires professional installation, the installation guide should be sufficient. 3.) FYI: RF Exposure. The distinctions between Mobile and Fixed are legal and not engineering common sense. For a TCB to approve a fixed device it must maintain a distance of at least 2 meters from all persons. For a TCB to approve a mobile device 20 cm (~8 inches) is sufficient. In addition, there is the September 2000 deadline for all equipment to meet RF exposure guidelines. Therefore for all practical reasons, there is no such thing as a ”Categorical Exclusion” anymore. Any questions please call or write. Bill William H. Graff Examining Engineer President and Director of Engineering mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

RF Exposure Info

RF Hazard Statement The instant device, a Part 15 spread spectrum transmitter, is a fixed device professionally installed inside an enclosed utility meter. Accordingly, the device is not to be used or sold to the general public. The antenna associated with the device is not external but is rather contained within the same utility meter enclosure. The device communicates with a fixed local area network. This transmitter does not fit within the definition of a “mobile device” set forth in section 2.1091(b) of the Commission’s rules Part 2, because it is to be used in fixed locations. Also, per Section 1.1037(b)(1), which is referenced by section 15.247(b)(4), categorically excludes this part 15 device from the requirements to conduct a routine environmental evaluation for RF exposure. In any event, based on the maximum output power and antenna gain information contained in the underlying equipment authorization application, the RF Hazard level form the antenna device are below the maximum exposure limits set forth in Section 1.1310.

RF Exposure Info

RF Warning Statement in Installation Guide WARNING While this device is in operation, a separation distance of at least 20 centimeters must be maintained between the radiating antenna and the body of all persons exposed to the antenna in order to meet the FCC RF exposure guidelines. This statement will be place in the installation guide were the installer can see it when performing final installation of the wireless utility meter.

Process Gain Measurement for Better LAN Transceiver (BLT) 1 of 4 Process Gain Measurement for BLT with FCC ID H6N26061200 Method The processing gain is measured using the CW jamming method. The equipment arrangement is shown in the block diagram below. Process Gain Tests Configuration Procedure A signal generator is stepped in 50kHz increments across the passband of the system. At each point the generator level required to produce a bit error rate equivalent to 2.7 x 10E-3, the threshold of designed performance for the system, is recorded as the jammer level (J). The output power of the transmitter is measured at the same point and recorded as signal (S). The jammer to signal ratio (J/S) is then calculated with 20% of the worst data points discarded. The lowest remaining J/S ratio is used to calculate the processing gain using the formula: Gp = (S/N)o + Mj + Lsys The theoretical probability of error vs. S/N is shown in the curve below, obtained from section 4.3.2 of Digital Communications, second edition, John G.
